Rare endocrine diseases are complex conditions that require lifelong specialized care due to their chronic nature and associated long-term complications. In Korea, a lack of nationwide data on clinical practice and outcomes has limited progress in patient care. Therefore, the Multicenter Networks for Ideal Outcomes of Pediatric Rare Endocrine and Metabolic Disease (OUTSPREAD) study was initiated. This study involves 30 centers across Korea. The study aims to improve the long-term prognosis of Korean patients with rare endocrine diseases by collecting comprehensive clinical data, biospecimens, and patient-reported outcomes to identify complications and unmet needs in patient care. Patients with childhood-onset pituitary, adrenal, or gonadal disorders, such as craniopharyngioma, congenital adrenal hyperplasia (CAH), and Turner syndrome were prioritized. The planned enrollment is 1,300 patients during the first study phase (2022–2024). Clinical, biochemical, and imaging data from diagnosis, treatment, and follow-up during 1980–2023 were retrospectively reviewed. For patients who agreed to participate in the prospective cohort, clinical data and biospecimens will be prospectively collected to discover ideal biomarkers that predict the effectiveness of disease control measures and prognosis. Patient-reported outcomes, including quality of life and depression scales, will be evaluated to assess psychosocial outcomes. Additionally, a substudy on CAH patients will develop a steroid hormone profiling method using liquid chromatography-tandem mass spectrometry to improve diagnosis and monitoring of treatment outcomes. This study will address unmet clinical needs by discovering ideal biomarkers, introducing evidence-based treatment guidelines, and ultimately improving long-term outcomes in the areas of rare endocrine and metabolic diseases.

Cell transformation induced by epidermal growth factor (EGF) and 12-O-tetradecanoylphorbol-13-acetate (TPA) is a critical event in cancer initiation and progression, and understanding the underlying mechanisms is essential for the development of new therapeutic strategies. Licorice extract contains various bioactive compounds, which have been reported to have anticancer and anti-inflammatory effects. This study investigated the cancer preventive efficacy of licochalcone D (LicoD), a chalcone derivative in licorice extract, in EGF and TPA-induced transformed skin keratinocyte cells. LicoD effectively suppressed EGF-induced cell proliferation and anchorage-independent colony growth. EGF and TPA promoted the S phase of cell cycle, while LicoD treatment caused G1 phase arrest and down-regulated cyclin D1 and up-regulated p21 expression associated with the G1 phase. LicoD also induced apoptosis and increased apoptosis-related proteins such as cleaved-caspase-3, cleaved-caspase-7, and Bax (Bcl-2-associated X protein). We further investigated the effect of LicoD on the AKT signaling pathway involved in various cellular processes and found decreased p-AKT, p-GSK3β, and p-NFκB expression. Treatment with MK-2206, an AKT pharmacological inhibitor, suppressed EGF-induced cell proliferation and transformed colony growth. In conclusion, this study demonstrated the potential of LicoD as a preventive agent for skin carcinogenesis.

Purpose: Healthy aging is an important concern in an aging society. Although the causal relationship between hypogonadism and erectile dysfunction in elderly men remains unclear, many physicians have achieved positive results after implementing exogenous testosterone supplementation therapy in patients with normal or slightly low blood testosterone. The purpose of this study was to conduct a systematic review and meta-analysis on whether testosterone replacement therapy (TRT) could improve sexual function in the elderly, as reported recently. Materials and Methods: As a comprehensive literature search was performed to find articles published in PubMed, Embase, and Cochrane databases by January 2022. The search used keywords of ‘aged’, ‘male’, ‘sexual behavior’, and ‘testosterone’. Randomized controlled trials (RCTs) were finally selected. As the main effect variable, results of a questionnaire on sexual function were analyzed and the effects of TRT were compared to those of placebo control. Results: Five RCT studies were included in this meta-analysis. The overall improvement by mean difference of sexual function for testosterone supplementation was 0.082 (95% CI: -0.049 to 0.213). In subgroup analysis, only intramuscular injection of 1,000 mg testosterone significantly improved sexual function of the elderly (0.229, 95% CI: 0.112 to 0.347). There was no significant difference in sexual function according to testosterone dose in meta-ANOVA (p=0.957). The difference was not statistically significant either in the meta-regression test (p=0.310). Egger’s regression coefficient test did not indicate a publication bias (p=0.132). Conclusions Although our overall effect size (that is, sexual function effect of TRT) did not show a significant improvement, the direction of improvement in erection and motivation was clearly shown. The injection formulation resulted in a significant sexual function improvement. Since only a few RCTs were included in the analysis, more well-designed prospective studies are needed to have a definite conclusion.

The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician’s decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology (KSGO) thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.

Iliac vein compression syndrome, which results in thrombosis of the left iliac veins, was first described by May and Thurner in 1957. May– Thurner syndrome should be considered when deep vein thrombosis-like symptoms appear, especially in the left lower extremities without an invasive procedure. The authors encountered an interesting case of a middle-aged female patient, who presented with sudden pain, swelling and skin color changes to the left lower extremity after right total knee arthroplasty and was diagnosed May–Thurner syndrome by computed tomography venography. This case is of clinical significance in that the early diagnosis of May–Thurner syndrome in the left lower extremity was made, which might have been overlooked after right total knee arthroplasty. This case is reported with a review of the literature review.

Purpose: This study aimed to investigate the relationship between femoral offset (FO) and clinical outcomes of patients with femoral neck fracture following bipolar hip arthroplasty (BHA). Materials and Methods: Records for a total of 520 patients who underwent BHA for a femoral neck fracture between December 1, 2003, and September 30, 2018, were reviewed retrospectively. Patients with unclear medical records, a congenital deformity and preoperative trauma history of the hip, high-energy multiple trauma, or a history of neurodegenerative disease or cerebrovascular disease were excluded. The remaining 77 patients included in the analysis had a minimum follow-up period of one year. For clinical assessment, the postoperative pain visual analogue scale (VAS) and Harris hip score (HHS) were analyzed at each follow-up period. For radiological assessment, the difference in leg length discrepancy (LLD) and FO were measured. Results: The difference in mean FO postoperatively was 6.7±4.8 mm, and the difference in mean postoperative LLD was 4.9±3.4 mm. The mean HHS was 77.1±7.7, 82.3±8.6, 83.4±7.7, and 86.4±6.7 at 1, 3, 6, and 12 months postoperative, respectively. The correlation coefficient between FO and HHS in 1-year follow-up was –0.38, and a statistically significant outcome was found (P=0.001). For the HHS domain, the correlation coefficient for function at 1-year follow-up was –0.42, revealing a statistically significant outcome (P=0.0001). Conclusion There was a statistically significant correlation between clinical outcomes and FO difference at 1 year after BHA in patients over 65 years of age with femoral neck fractures.

Background: Patient-centered management is becoming increasingly important in gout, but there are limited studies exploring patients' perspectives and preferences. We aimed to investigate patients' perspectives and preferences regarding gout and gout management, and their impacts on adherence to urate lowering therapy (ULT). Methods: A paper-based survey was performed in patients with gout seen at the rheumatology outpatient clinics of 16 tertiary hospitals. The survey included questions regarding demographics, comorbidities, gout attacks, current treatment and adherence, and patients' perspectives and preferences regarding gout and gout management. Multivariate regression analysis was performed to determine the factors associated with ULT adherence. Results: Of 809 surveyed patients with gout, 755 (94.5%) were using ULT. Among those using ULT, 89.1% had ≥ 80% adherence to ULT. Majority of the patients knew management strategies to some extent (94.8%), perceived gout as a life-long disease (91.2%), and were making efforts toward practicing at least one lifestyle modification (89.2%). Most patients (71.9%) obtained information about gout management during their clinic visits.Approximately half of the patients (53.6%) preferred managing their disease with both ULT and lifestyle modification, 28.4% preferred ULT only, and 17.4% preferred lifestyle modification only. Adherence was better in patients with older age (odds ratio [OR], 1.03), those with better knowledge of gout management strategies (OR, 3.56), and those who had preference for ULT (OR, 2.07). Conclusion Patients' perspectives and management preferences had high impacts on adherence to ULT in gout. Consideration of patients' perspectives and preferences is important for achieving the desired clinical outcome in gout.
